APPARATUS FOR UTILIZING THE HEATED FUMES FROM A SMEL[1112112. OR ORE-FURNACE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Original application filed April 22, 1912, Serial No. 692,525. Divided and this application filed March 16, 1914. Serial No. 824,992.

To all whom it may concern Be it known that I, GUSTAV P. LUEDKE, a citizen of the United States, residing at Chatham, in the county of Sangamon and State of Illinois, have invented a new and useful Apparatus for Utilizing the Heated Fumes from a Smelter or Ore-Furnace, of which the following is a specification.

The present invention relates to improvements in an apparatus for utilizing the heated fumes from a smelter or ore furnace, the present application being a divisional application of an application filed April 22, 1912, Serial No. 692,525, covering apparatus for condensing noxious gases and utilizing the heat therefrom, one object of the present invention being the provision of an apparatus, in which the heat from the noxious gases is used to distil water for use in making pure chemicals or for heating water for any purpose, a flue for the noxious fumes being disposed about the water reservoir or tank and being provided with a lower compartment for the reception of the precipitants such as arsenic trioxid and zinc oxid which are deposited from the fumes in their passage from the smelter through the apparatus as particularly set forth in the above mentioned application.

A further object of the present invention is the provision of an apparatus of this character, in which the fumes and heat conducting flue is divided into a plurality of compartments, each of which is controlled by its individual damper, so that the heat may be directed to and concentrated at a particular point upon the water tank or reservoir.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a perspective view of the present apparatus, portions of the same being broken away to show the interior construction. Fig. 2 is a transverse cross section through the apparatus. Fig. 3 is a detailed iew showing the damper conparticularly illustrated in Fig. 2. The space below the grating 3 constitutes the chamber for the reception of the precipitant, which in the employment with the noxious gases for heating the present apparatus, consists primarily of arsenic trioxid and zinc oXid. In order to provide a means for directing the fumes through the respective lines, so that any number may be cut in or out, the dampers 6, 7 and 8 are employed, the same being manipulated from the outside so as to be readily regulated as necessary.

The vertically disposed tank 8 is disposed upon the colu nm 7 above the grate 3 and thus intermediate of the flues 5, so that the heat and the noxious gases are caused to flow therearound to properly heat the surface of the tank and the water therein.

The side walls 11 are constructed of brick so as to properly confine the fiues and thus make the apparatus more durable.

The inclined chamber 12 which is at the outlet of the fiues 5 and 5, opens into the outlet 'flue 13, which as indicated in the above mentioned application directs the fumes to other parts of the apparatus.

Mounted in the brick work at the sides thereof adjacent the chambers below thegrating 3 are the doors 14, by means of which the precipitant may be removed when necessary.

From the foregoing description, it is evident that with the dampers 6, 7 and 8, the fumes arising through the grating and into the chamber 4 may be directed at various heights relatively to the tank or reservoir 8, so that the heating action thereupon will be regulated, the grating 3 throughout constituting a means whereby the condensed fumes will be directed into the chamber therebelow for removal. The heated fumes contacting the walls of the water tank 8 are condensed to a great degree and thus a certain amount is precipitated during the movement ofthe fumes through the present apparatus.

What is claimed is:

1. An apparatus of the character described, including a casing having an enlarged central portion and oppositely inclined portions leading toward the bottom thereof, a grate disposed within the casing and forming a precipitant chamber therebelow, a fume directing flue entering one end of the casing at the lower inclined portion thereof and below the grate, a fume directing outlet flue disposed at the opposite end of the inclined portion of the casing above the grate, a vertically disposed reservoir mounted above the grate in the enlarged portion of the casing, said reservoir being spaced from the walls of the casing to provide a plurality of auxiliary flues, and selectively controlled dampers one for each of the latter flues.

2. An apparatus of this character, including a casing having a main chamber provided with diverging walls extending in opposite directions from the top thereof,

a grate bottom for the chamber and providing a precipitant chamber therebelow, a flue having a plurality of vertical partitions opening below the grate at the inlet end of the casing, an outlet flue at the opposite end of the casing and wholly above the grate, a cylindrical vertically disposed water container mounted centrally of the casing and spaced from the walls and above the grate thereof, a vertical partition extending J N0.
